Jeff of Maryland said this "I have ordered these copepods and amphipods several times, and each time I am amazed at the biodiversity in the bags! My dragonette is a pig, and he can eat quite a few of these little guys, but once introduced to my fuge and display tank, they don't need repopulating very often because of how well they reproduce. Reefs2go is an incredible company, and customer service is impeccable!"
